METAL s'roaasn-rnnm Toull whom it may concern:

Be itknown that I, JEFFERSON D. HARRY, a citizen of the United States,residing at Dallas, in the county of Dallas and State of Texas, haveinvented certain new and useful Improvements 1n- Metal Storage-Tanks, of

which the following is a specification.-.

This. invention has relation to metal stor age tanks and particularlyftoknock-down tanks. y

The object of thefmventio n is to provide a tank formed in-severalsections or parts and arranged to be assembled in an expeditiousandsubstantial manner. 1

Another feature is a particular form of gether and held in permanentrelation.

F mally the object of. the invention is to provide a tankof thecharacter described thatjl'will be strong, durable, eflicient, and lightin weight, comparatively inexpensive to construct; and one in which theseveral parts will' not be likely to get out of working I order.

With the abovevand other objects in View, the invention has relation tocertain novel featuresof construction and operation, an

example of which is described in this specification andillustrated inthe accompanying drawings, wherein: Figure 1 is an elevation of .thetank'assembled, Fig. 2, is a partial vertical section, ig. -3, is adetail of one of the clamps in perspective, and Fig. 4 is a detail insection of a" modified form.

In the drawings, the numeral 1 designates one of-the side sections ofthe tank, 2 the bottom sections, and 3, the top sections. The

members 4 and 5 are preferablyformed of A The clamps are made in singleand double wood to make the section as light as possible, although othersuitable material could be used if desired.

Each frame has a panel or innercovering ably fastened to the inner sideof the. frame.

be adjusted to draw the members and a tank so assembled that thesections of one course break-joint with those ofthe next ad aoentcourses.

The edge. portions or outwardly directed fflanges 7 of one. section areopposed to the corresponding portions of the adjacent sections, andbetween the sections, a suitable packing, 8 may be disposed bothvertically and horizontally. When the sections aredrawn together thispacking will be compressed and the liability of the tank leaking reducedto a minimum.- The bottom sections '2, also each have a frame, whichhowever is composed of segmental members 9 connected by cross members 10at their ends, but said cross members lying in the same plane as themembers 9; The bottom sections are of course disposed horizontally andeach has such a length as to produce a circular base when the saidsections are all in place. Each bottom frame has a covering 11 of sheetmetal having downwardly directed flanges 12 embracing the sides of thecross members 10. The sheet metal of the bottom is merely ex tended overthe members '9 as shown at the right of Fig. 2. Wherever sections arebrought together, the packing 8 is interposed. If a lock-joint isdesired between the lowermost sections 1 and the bottom sections, theflanges 7- 0f the lower members. 4 are extended outward and bent up asshown at the left of.Fig. 2. The edge portions 14 of the bottom sheetmetal coverings 11 are bent up and about the bent portions of theflanges and a folded sea-m produced. Such an arrangement will not onlystrongly, connect the bottom and side sections, but provide awater-tight joint.

For holding the sect-ions together, I provide a plurality of clamps.Each clamp comprises two members 15, each having an eye 16 and theadjacent edges of the members overlapping, whereby a bolt 17 passedthrough the eyes and held by a nut 18 may of a clamp together or permitthem to be moved apart.

collar. These clamps are disposed as is best snown in Fi s. 1 and 2, theopposite members either engaging the adjacent members or the adjacentmembers 4 of the side sections 2 and the segmental members 9 of thebottom sections. lVhen the members are placed in position, the tonguesbeing tapered may be readily inserted between the wood frame members andthe sheet metal covering, thus holding each individual member inposition on its respective part which it embraces. The double clampmembers are used at the intersection of two members 5 and two members 4or at the intersection of two members 5 and the bottom members 4 and 9.In the double. clamps one of the members 15 as shown in Fig. 3 has anangular collar which embraces the members 5 and ties them together.

The sections 3 at the top of the tank radiate from a center stud 21 andeach section has radial members 22 along its edges, extending from thestud. Each section is formed of sheet metal 23 secured to the radialmembers and turned down at its outer edge to form a segmental flange 2afitting over and fastened to the upper segmental In Fig. 4 I have showna modified form,

of tank. This tank is designed for storing crude oil and material whichwould corrode or injure the sheet metal coverings. The generalconstruction of the tank is the same, the main difference being in alining 25 of soft metal, as lead which is applied to the inner surfaceof the sheet metal and the flanged portions of the same.

IVhat I claim is: w

1. A knock-down tank comprising a bottom, a top, a sectional cylindricalbody, the sections forming the body each comprising a wooden framehaving vertical and horizontal members, and a sheet metal coveringhaving its edge portions bent about the frame, and two part clampsembracing the adjacent members of adjoining sections, the clampsspanning the members transversely.

2. A knock-down tank comprising a bottom, a top, a sectional cylindricalbody, the sections forming the body each comprising a wooden framehaving vertical and'horizontal members, and a sheet metal coveringhaving its edge portions bent about the frame, two part clamps embracingthe adjacent members of adjoining sections, the clamps spanning themembers transversely, anda packing interposed between the sections. v

3. A knock-clown tank comprising a bottom formed of sections each havinga frame covered with sheet metal bent thereabout, a sectionalcylindrical body, the sections of the body each comprising a framecovered with sheet metal bent thereabout, a top formed of sections eachcomprising sheet metal secured to the side sections and having radialmembers, and two part metal clamps embracing and extendingtransversely'of the members of adjoining frames
